Abstract
A hanging prevention roller is installed between a first suction conveyance unit on an upstream side and a second suction conveyance unit. When an inspection object is sent from the first suction conveyance unit into the second suction conveyance unit, a top edge of the inspection object abuts on and runs on the hanging prevention roller before the top edge of the inspection objects hangs down under its own weight or due to downward curling and so forth, the top edge is sandwiched between the roller and the second suction conveyance unit, and thereby stable suction conveyance is started without delay.
